On the contrary, A man can love his own love, and can grieve at his own sorrow. Therefore, in like manner, he can fear his own fear.
I answer that, As stated above (A. 3), nothing can be an object of fear, save what is due to an extrinsic cause; but not that which ensues from our own will. Now fear partly arises from an extrinsic cause, and is partly subject to the will. It is due to an extrinsic cause, in so far as it is a passion resulting from the imagination of an imminent evil. In this sense it is possible for fear to be the object of fear, i.e. a man may fear lest he should be threatened by the necessity of fearing, through being assailed by some great evil. It is subject to the will, in so far as the lower appetite obeys reason; wherefore man is able to drive fear away. In this sense fear cannot be the object of fear, as Augustine says (QQ. 83, qu. 33). Lest, however, anyone make use of his arguments, in order to prove that fear cannot be at all be the object of fear, we must add a solution to the same.
Reply Obj. 1: Not every fear is identically the same; there are various fears according to the various objects of fear. Nothing, then, prevents a man from keeping himself from fearing one thing, by fearing another, so that the fear which he has preserves him from the fear which he has not.
Reply Obj. 2: Since fear of an imminent evil is not identical with the fear of the fear of imminent evil; it does not follow that a thing flies from itself, or that it is the same flight in both cases.
Reply Obj. 3: On account of the various kinds of fear already alluded to (ad 2) a man's present fear may have a future fear for its object. ________________________
FIFTH ARTICLE [I-II, Q. 42, Art. 5]
Whether Sudden Things Are Especially Feared?
Objection 1: It would seem that unwonted and sudden things are not especially feared. Because, as hope is about good things, so fear is about evil things. But experience conduces to the increase of hope in good things. Therefore it also adds to fear in evil things.
Obj. 2: Further, the Philosopher says (Rhet. ii, 5) that "those are feared most, not who are quick-tempered, but who are gentle and cunning." Now it is clear that those who are quick-tempered are more subject to sudden emotions. Therefore sudden things are less to be feared.
Obj. 3: Further, we think less about things that happen suddenly. But the more we think about a thing, the more we fear it; hence the Philosopher says (Ethic. iii, 8) that "some appear to be courageous through ignorance, but as soon as they discover that the case is different from what they expected, they run away." Therefore sudden things are feared less.
